  182. # Contemporary Android applications can provide multiple JNI
  183. # providers in .apk, targeting multiple architectures. Among
  184. # them there is "place" for two ARM flavours: generic eabi and
  185. # armv7-a/hard-float. However, it should be noted that OpenSSL's
  186. # ability to engage NEON is not constrained by ABI choice, nor
  187. # is your ability to call OpenSSL from your application code
  188. # compiled with floating-point ABI other than default 'soft'.
  189. # (Latter thanks to __attribute__((pcs("aapcs"))) declaration.)
  190. # This means that choice of ARM libraries you provide in .apk
  191. # is driven by application needs. For example if application
  192. # itself benefits from NEON or is floating-point intensive, then
  193. # it might be appropriate to provide both libraries. Otherwise
  194. # just generic eabi would do. But in latter case it would be
  195. # appropriate to
  196. #
  197. # ./Configure android-arm -D__ARM_MAX_ARCH__=8

  205. # -march and/or -mfloat-abi flags. NDK defaults to armv5te.
